CommunicationError

What am I doing wrong?

using_a_function.py
"""
This is importing a function named `tweet` from a file
    that we unfortunately don't have access to change.

You use it like so:
>>> tweet("Hello this is my tweet")

If the function cannot connect to Twitter,
    the function will raise a `CommunicationError`
If the message is too long,
    the function will raise a `MessageTooLongError`
"""
from twitter import (
    tweet,
    MessageTooLongError,
    CommunicationError,
)


message = input("What would you like to tweet?  ")
# Your code here
try:
    tweet(message)
except CommunicationError:
    print('An error occurred attempting to connect to Twitter. Please try again!')

I'm not seeing anything "wrong" here. This code passes tasks 1 and 2 as it is. And the code for task 3 just has not been added yet.

Hi Piotr Manczak,

I think that you do not need to handle any error here using try and except... You just need to use the functions you are importing. For instance:

from twitter import (
    tweet,
    MessageTooLongError,
    CommunicationError,
)


message = input("What would you like to tweet?  ")

if #whatever condition that makes the message too long:
    MessageTooLongError(message)
elif #whatever condition that produces a communication error:
    CommunicationError(message)
else:
    tweet(message)

I hope this helps, anyway you can ask me again.

Cheers
